Hey there, before going ahead with your map submission review I'd like to inform you that I'm only giving you my personal opinion/feedback on your parkour map submission and my personal feedback will certainly not affect your parkour map submission in the slightest, I recommend that you take in my feedback to improve your submission if there are any flaws, you don't need to and you're free to ignore me but anyhow, before going ahead I'd like to mention that I'm a Moderator not a Map Judge so this is just my personal opinion and I am not accepting or denying your parkour map as this is only my personal opinion.
Parkour theme/detail: Your parkour theme by the looks of it is 50/50 on originality, I've seen some tower maps but not really any modern looking ones, for your parkour detail it's pretty basic, you did a decent job on the outside but it still feels kind of plain and basic for a tower.
Parkour difficulty/variety: For your parkour difficulty I would say it's a medium parkour map submission, nearing the end of your map you've got an insanely hard parkour jump which I don't even know if it's possible or not, you'll know it when you see it, it involves a slab parkour jump, I recommend changing that. Your parkour looks messy as a majority of it is necessarily floating throughout the interior of the tower, your parkour variety is very basic and you didn't really use any memorable or unique parkour jumps, I recommend adding flower pot jumps, chest/enchantment table jumps, etc to spice your map up.
Good luck!
